The MASS test is one of seven EEI tests. It was developed to serve as an employment selection test in the plant maintenance field. More than 40 electric utility companies took part in a four-year study to develop the test. The study was directed by the Personnel Decisions Research Institute of Minneapolis, Minnesota and began in 1981. Job and cost/savings analyses and performance ratings were included in the research. Based on this research, the MASS test is able to estimate the probability of a candidate's success in the following categories related to plant maintenance jobs:

Assembling Objects (20 questions/15 minutes)This test assesses one's ability to visualize the properly assembled form of an object. A diagram featuring parts of an object is presented, each part labeled with a letter. Candidates are required to assemble the parts so that ones with corresponding letters are put together. The test consists of 20 multiple-choice questions and has a 15-minute time limit.

Mathematical Usage (18 questions/7 minutes)This test assesses one's ability to work out basic mathematical problems using the information provided at the beginning of the test. The test includes 18 multiple-choice questions and must to be completed within seven minutes.

Reading Comprehension (36 questions/30 minutes)This test assesses one's ability to read and comprehend written materials generally found in power plant training manuals. The test taker is presented with five passages and several follow-up, multiple-choice questions. The test includes 36 questions and must to be completed within 30 minutes.

MASS Scoring

The scores from the four MASS aptitude tests are combined into a Cognitive Index Score. This score allows for potential employers to predict the probability of a successful job performance.

It's also important to note that there is no penalty for guessing or wrong answers.
